Two boys, both of the same weight, sit on each side of a see-saw (跷跷板）. How far must they be from the centre in order to keep the see-saw balanced(平衡的) ?

By moving to different positions, they will soon find out that they have to sit at equal distances from the centre. Now, if one of them is heavier, the heavier boy has to be nearer to the centre to make the see-saw balanced.

Things to do:

Take a stone in each hand. Can you find out which stone is heavier? If the two stones are about the same size, you may not be able to tell which one is heavier. Place a pencil on two piles of books and balance a ruler and move them until the ruler is balanced. Find out how far each stone is from the pencil. The stone nearer to the pencil is the heavier one. Now you know a simple weighing machine （秤）works.
